Here's a new image of a conspicuous square mesa that appears possibly artificial. (I devote a lengthy commentary about this feature and nearby formations on my Cydonian Imperative site and in my Mars book.)

The square mesa could be compelling evidence that symmetrical "platforms" like that beneath the "Face" are produced through natural processes. Or it could be further evidence of artificial construction on Mars' surface. It's an intriguingly elliptical problem, and one that I don't foresee going away in the near future.
